To all wzpm it may concern:

e it known that I',V1LLIAM'CLEI\0W, a.

citizen of the United States, residing at Car--` v bondale, in the county of Lackawanna and f State of Pennsylvania, have invented certain f new and useiul improvements n Excavat- .ing-lwiachines; and l do declare tie following to be a full, clear, and exact description-of the invention, such as will enable others skilled inthe art to which it appertains vto make and use the same.

This invention relates-tov excavating ma ,clunes and has tor its ob3ect to provide an arrangement whereby the lordinary steel scoop may be drawn by power operated means instead or by draft animals;

, Another object is; to provide a device of this kind ya'fliereby the scoops may be drawn by a cable Wound around a drum, said drum being driven in any suitable manner by power.

Anotl'ier object is to provide a device of this kind whereinthe drum operating mechanism is combined with the drum so that the various parts of the device are mutually held ing machine is an embodiment i do not linut myseli to the minute details oi the :construction and, the airstngement hereinafter described, but reserve they right 'to make such changes as lie Within the spirit andscope of the invention.

in the annexed drawings, Figure 1 is a top. plan viewv of my complete device, and Fig. 2 is a aide elevation ci the same,l

The vembodiment oi my invention consists ci the herein shown excavating machine comprising asupporting frame i, on which are mounted winding' drums 2 and 3 on which is wniund the cable i passed over'the end drum 5. @n tbe cable intermediate the drums 2 and 3 andthe drum 5 are fastened .at any convenient point 'the scoops 6,' by means o' chains or the llike 7. The drum ..5 rotatably supported inl any convenient manner 1n a shaft 8', said shaft being sup-l p1- ed byV bottomand top pieces 9 and 10 connected by theside'brace 11. vThe drumsand l may be connected to the source of power the crank shaft 1 2 of an engine suitable manner, but the arrangement herein shown is preferred because of advan tages which will heremaftcrappear.

The drums 2 and 3`arev r'ovided with suporting shafts 13y rotat'ab y mounted in the' caring box, mounted on outer side members 15, and inner parallel members 16. Saul.

parallel members are also provided with bear ing boxes 17, adapted to rotatably su )port the ycrank shaft 12, and between which the connecting link 18 reciprocates. The crank shaft 12 is provided at each end with pinions 1.9-, adapted to intermesh -2() of the gears 21.

At the inner ends of the drums 2 and 3 it will be noticed that the drums 2 and 3 are not in alinement with eachother, but are so arranged'that the gea-r teeth 20 iutermesh with the pinions 19 on opposite sides-of the axis of the crank shaft 12. This is advantageous because the drum 2 tends to hold the crank shaft 12 from displacement in one direction ,While the dru'mB tends to hold the crank shaft against displacement in the opposite direction. in this way the crank shaftis heldin place much more securely and ,with less required strength, and therefore cost, of the supporting frame. The outer side pieces 15 are held inspaced relation with the parallel members ,16, by means of end pieces 22 and angular-ly disposed braces 23. This in combination with the peculiar arrangement of the drums relative to the crank shaft forms a very strong and eilicient supporting frame.

The frame as thus described is duplicated by al lov/er'supporting frame 2a, to which the upper frame 1' is connected -by uprights 25 p aced under the meeting points of various members of v'the upper trame 1. The engine operating the connecting link 18 is not shown, as it forms no part of this inventionand any convenient source of power may be substituted thereior it Will be noticed that the cable 4 meets the drum on the upper side, and the drum 2 on the lower side. In this-manner as is obvious when the engine is run the cable is wound onto one drum andl ofi the other, thus moving continuously toward one drum. When the engine is reversed the movement of the cable reversed. l' The operation of my machine is as follows: The drum 5, is placedl at a convenient distance''romtbe 'frame 1, 'thematerial to be excavated or removed lying at some point intermediate the ends ojthe' cable,prelerwith the gear teeth" ably nearer the'drum 5 orl the frame 1.' For example We Will say that the material to be y removed 1s nearer the frame 1, the :engine is4 noW started to cause the scoops 6 to move ina forward direction. The'materialt be removed is scooped into the scoo 26 and i the direction of the motion of the engine, or-

by allowing the scoops to pass' around the vend drum 5.

drawn by means of the chains 7 an cable 4 until the material is carried tothe point at Which it is wished that the material be dumped, say for exam le near the drum 5. It Will be understoo that the materialto be removed may be carried'either toward' or from the frame 1 or the frame 5 by reversing It is -thought that the o eration and advantages of my 'device .be understood Without further description- I claimz- 1. Incombination, a supporting structure,

drums rotatably mounted on said su porting structure, said drums being place out of alinement With each other, gears on the inner ends of said drums, a shaft provided with pinions 'adapted to intermesh With said gears,

said gears intermeshing With said pinions on opposite sides of the axis of said shaft,

means to rotate said shaft, and means Wound around said drum adapted to direct the excavating means.

consisting ofparallelmembera and outer n combination, a supporting'ii-rameI side pieces, end pieces and braces connecting l said side pieces and saidjparallel members, drums rotatably mounted between said-"side pieces and said parallel members, one ofsaid .drums being mounted -forwardl of the other 'one end Wound in one `direction around one .of sald drums andthe other end Wound 1n the opposite direction around the other of said drums, .an end'drum over whichv the interv meshing part of said cable isadapted to pass, a shaft to said drum bottom and top pleces supporting said shaft and side ,bracescon4 necting said to and bottom pieces, chains v fastened to sai cable to scraper scoops fastened. totheiree ends of said chains.

In testimony whereofl have hereunto set aft intermeshing with the gears of said my hand in presence of tWo subscribing Wit- ,A

nesses.
